I'm sure there are doctors around here... I am not sure how healthy it is to cycle all the time in an antibacterial soup. Essentially this is working, according to your reports, because there is an AB residue on everything. It seems to be an oversimplified view that all bacteria is bad. A lot of skin surface bacteria has a job to do. Not normally considered all that healthy, not to mention the fact those soaps are a persistent poison in the environment. That means they shouldn't be used to wash in natural water course. The main point though, is that you don't need some poison to stay OK along a tour.
